PIN CONNECTIONS DESCRIPTION The HCC4089B (extended temperature range) and HCF4089B (intermediate temperature range) are monolithic integrated circuit available in 16-lead dual in-line plastic or ceramic package. The HCC/HCF4089B is a low-power 4-bit digital rate multiplier that provides an output pulse rate that is the clock-input-pulse rate multiplied by 1/16 times the binary input. For example, when the binary input number is 13, there will be 13 output pulses for every 16 input pulses. The HCC/HCF4089B has an internal synchronous 4-bit counter which, together with one of the four binary input bits, produces pulse trains as shown in timing diagram. If more than one binary input bit is high, the resulting pulse train is a bination of the above separate pulse trains. This device may be used to perform arithmetic operations (add, subtract, divide, raise to a power), solve algebraic and differential equations, generate natural logarithms and trigonometric functions, A/D and D/A conversions, and frequency division.
